//! `aura-std` — the standard node library shipped with the engine.
//!
//! The universal, batteries-included building blocks every project gets for
//! free: common indicators (SMA, ATR, RSI, …), resamplers, the `SessionNode`,
//! standard combinators, the legacy `SimBroker` pip yardstick, and cost-model
//! nodes authored against the [`CostNode`] trait + [`CostRunner`] adapter
//! (`ConstantCost`, `VolSlippageCost`, …, in R — C10). Depends only on `aura-core`
//! (the shared contract).
//!
//! This is the top tier of the three-tier node-reuse model (contract C16):
//!
//! - `aura-std` — universal blocks, here, ship with the engine;
//! - shared node crates — cross-project-reusable blocks, in their own repos,
//!   pulled in as cargo git dependencies;
//! - project-local `nodes/` — experimental, project-specific blocks.
//!
//! The first block lands with the walking skeleton: [`Sma`], the simple moving
//! average — a worked producer node proving the `aura-core` `Node` contract.
